Tissues And Hormones Of The Endocrine System (Lab Report Sample)

Instructions:

Tissues and Hormones of the Endocrine System
This is a Hands-On Labs exercise that explores what the tissues of the endocrine system look like at low-, medium-, and high-power magnification. The tissues include the pituitary gland, the thyroid gland, the adrenal gland, the pancreas, the ovary, and the testis. Images with different tissues and structures are provided for you to a label. You will also assess the differences between tropic and non-tropic hormones, and then write a lab report or create a presentation.
Procedure
Complete both exercises in the Hands-On Labs experiment about the endocrine system by labeling images and filling in tables. You do not need to submit the Lab Report Assistant. Instead, write up a lab report or create a presentation.
Create a Report or Presentation
Use the following outline to describe the data from your lab in a report or presentation. Label each portion of the lab as described below.
Introduction: Start with a broad discussion of the topic. Why is this topic of interest? What will you learn? Discuss specific items that this lab explores. What are you comparing and what are some differences you expect to see?
Material List: Identify all items that you used and the exact quantities, as applicable.
Methods: Describe how you conducted the experiment, including any safety precautions you took while performing the lab. Be sure to include any changes that you made to the original instructions. This should be a short, paraphrased version of the methods from the lab. Do not copy from the lab; Turnitin will highlight it as plagiarism.
Results/Data: Insert all images and tables from the lab here, including a brief statement about each one.
Discussion: Review what you observed, including a brief discussion about every tissue examined. What differences did you notice as you explored the magnified tissues? What types of hormones do the tissues secrete and where do they act? What do they do? What other differences or interesting characteristics did you notice while performing this lab?
Conclusion: End with a section describing what was particularly interesting to you in this lab; identify errors that may have impacted your results, or note errors in the lab itself; and provide recommendations for future labs.

Introduction
The Endocrine system is one of the most essential parts of the body. Its functions encompass almost every aspects of our body's functioning and regulation – from sleeping, metabolism, mood regulation, and reproduction among others. Structurally, this whole system consists of eight (8) major glands together with the pancreas that functions for hormone secretion and digestion, respectively. Hormone secretion is crucial for the body as these chemicals could either act as an inhibitor or stimulator, through the process of feedbacks that then maintains the body's homeostasis. In this lab experiment, the researchers conducted a more in-depth study of the structure and function of the system. Particularly speaking, the focus would be on the different cells that make all of these processes possible. Its structures, functions and the specific regulatory mechanisms would be examined in further detail and compared to one another. In the succeeding section of this study, a focus on the origins of both tropic and non-tropic hormones, their target tissues, and its effects would also be described. Although, it would only be the structure that would be focused on the staining process of the experiment. All in all, the researchers believed that by knowing the very structures of these cells, it would be easier to understand the very processes that are ongoing and keeping us alive.
Material List:
No materials are required for this experiment
Methods:
The experiment starts with procuring a microscope and the samples of different endocrine cells. After securing these a well-lit spot was found in order to provide a better magnification of the samples. Throughout the whole process, the order in which the samples were studied was from low to medium, and to the highest magnification in order to provide a clearer view of the whole structure. All of them were also labeled based on the structures found. The order and the specific structures of each sample that was examined are given below.
1 Pituitary Gland – Anterior; acidophil cells and basophil cells. Posterior; Nucleus of the Pituicyte.
2 Thyroid gland – Follicular Epithelial cells and Colloid
3 Adrenal Gland – capsule, zona glomerulosa, medulla, zona reticularis, zona fasciculate
4 Pancreas – Islet and Acinar Cells
5 Ovary – Follicles
6 Testes – spermatogonium, spermatocytes, and Leydig cells
To provide a better representation of the structures, the researchers tabulated the results. Lastly, supplementary analysis of these structures was also done.
Results/data:
Photo
Pituitary Gland
Label: acidophil cell, basophil cell, and nucleus of pituicyte
The acidophil cells are those which are strongly stained and have more developed outlines. The Basophils have large black spots for their “secretory granules”. The nucleus of the pituicytes are the smaller ones
Thyroid gland
Label: follicular epithelial cells, colloid
The Follicular Epithelial cells are the ones that are surrounding the colloid. Colloid is cThe collided.
Adrenal gland
Label: capsule, zona glomerulosa, medulla, zona reticularis, zona fasciculate
The capsule is in the outermost part of the circle (cell), followed by the Glomerulosa, Fasiculata
